implemented with artoolkitplus

but the up vector does not sync together

any hints?

Hi, I'd be interested to see your code, can you make a post on the openFrameworks forum with your code? It is hard to tell from the video why this is happening.

just found that it was the fbo upside down issue

fboRender.draw(0,0,ofGetWidth(),ofGetHeight());

replace with

fboRender.draw(0,ofGetHeight(),ofGetWidth(),-ofGetHeight());

may be it works
